What problem does it solve? Node.js developers often default to familiar frameworks and patterns without evaluating whether they fit the project's deployment target, performance needs, or team context. This Skill provides decision-making frameworks for architecture, async patterns, validation, security, and testing so choices are grounded in actual requirements. ## Core Features & Use Cases - Framework Selection Guidance: Decision trees and comparison tables for Hono, Fastify, Express, and NestJS based on deployment target, cold start needs, and ecosystem maturity. - Architecture & Async Principles: Layered structure (controller/service/repository), event loop awareness, and guidance on when to use Promise.all, allSettled, or worker threads. - Security & Validation Checklists: Input validation boundaries, library selection (Zod, Valibot, ArkType), and a security checklist covering hashing, JWT, rate limiting, and secrets management. - Use Case: When starting a new serverless API, use this Skill to evaluate whether Hono fits the edge deployment target, plan the layered structure, and define the validation and error-handling strategy before writing code. ## Quick Start Ask the AI to help you choose a Node.js framework and architecture for your project, describing your deployment target and performance requirements.
